To all whom it may concern:

Be it known that I, PHILIP T. SHARE, of Ba timore city, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Sash-Locks; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a plan view, showing the under side of the lock and keeper. Fig. 2 is a longitudinal vertical section in line 2 z of Fig. 1. Fig. 3 is a transverse vertical section in line a: w of Fig. l; and Fig. 4 is a transverse vertical section in line y y of Fig. 1.

Sim lar letters of reference in the accompanying drawings denote the same parts.

This invention, which is an improvement upon a former one patented to me October 11, 1870, No. 108,194, has, among others, the- .as the latter is turned around, it will both look the sashes to each other, and simultaneously therewith draw them tightly together; and also '1 so constructing the bolt and guides that they will gnide'the end of the bolt accurately into the keeper, allow it to turn only when it is in position for looking or unlocking, and hold it at two places when locked, substantia ly as I will now proceed to 3 describe.

In the drawings, E is the bolt, having an enlarged cylinderhead, E. eis a pin project n g latera y from said enlarged head. 0 is a thumb-piece, fastened in any suitable manner to the outer end of the bolt; and c is a socket fastened by a set-screw or otherwise upon the bolt adjacent to the thumbpiece, and provided with a right angled slot or recess, a a. H is the case or housing in which said bolt is held, it being made with an ornamental exterior, and adapted to fasten upon the top of the inner sash, with the handle projecting inward, and being provided with walls It 71, -]L2, which support and guide the bolt. S is a spring arranged between the wall h and the end of the socket c, and serving to retract the bolt when the latter is unlocked. K is the keeper, the end wall k of which is provided with-a round opening having alateral recess, 0, to fit the end of the bolt; also, allow the pin 0 to pass through when the bolt is presented in one direction, but notwhen presented in any other direction. 'iis an incline on the inner side of the wall It, at that side of the slot 0 toward which the pin 6 is free to turn when said pin has passed in through wall k. m is a projecting spur on the inner side of the wall h which or tends into the right-angled slot to, and guides the movements 'of the bolt, and serv ng also to lock the bolt at one end, while the pin 0, engag ng behind the wall It, looks it at the other end.

The operat on of this com bi ued sashlock and tightener is as follows: When in the position shown in Figs. 1 and 2 the bolt cannot be turned, by reason of the spur m extending into the straight portion a of the slot at a; but,

when the bolt is pushed forward so that said spur enters the circumferential part a of said slot, as shown in Fig. 1, then it is i'ree to turn, and, when turned, cannot be drawn back, by reason of the spur engaging with the slot to prevent it. When tu ned back, however, so

that the spur comes in line again with the 'si raight part a of theslot, the spring 8 throws the bolt out at once, and unlocks the sashes.

The notches in walls h and is, which permit the p n 0 to pass through, are so arranged that the pin ecomes exactlyin line with them when the spur m is in line with the part a of slot at a, andtheresult of this is that said metal walls allow the end of the bolt to slide freely back and forth, to lock or unlock the sashes so long as the spur m is in the part a, and that by the time when the spur comes to the part a of said slot the pin 0 will have passed through both walls, and be ready to look behind the wall it. The movement of the bolt, therefore, which causes the spur m to enter the curved portion a of slot a a, also causes the pin 0 to pass out of range of slot 0, and locks the bolt so that it cannot be disengaged from the keeper till turned back to its former position; but, as thepin passes thus out of range of the slot 0, it rides up on the incline 1', which causes the two meeting-rails to be drawn tightly together, and. keeps the sashes from rattling.

I claim as my invention- The combination of keeper K, case H, incline a, bolt E, pin e,' spur m. and right-angled slot on a, substantially as and for the purposes set forth.
